Fighting superhuman-level opponents requires a bit of courage and a touch of combat wisdom. If it were those BBA company combat bioroids, Li Pan would definitely not dare to attack head-on.
After all, when they get fierce, they're really capable of a tenfold overload kamikaze kick, treating your head like a ball, kicking it dozens of yards away.

A flip or two occasionally might be a personal problem, too inexperienced or too reckless. But if one persistently keeps flipping, that can only mean that this system is flawed, and its potential is misdirected, isn't it?
